- Desiccating Fluids,

Be it known that I, Crmnnns E. Boenns,

a citizen of the United States, residing at,

Detroit, county of Wayne, .State of Michigan, have invented Improvement in Meansffor and Methods of ing to be a full, clear, and exact description of the same, such as willenable othersskilled in the'art towhich it pertains to screens 8,- 8, pivoted at the bottom 9. and

make and use the same, reference being had tothe accompanying drawings which form a part of this specification r This invention relates to a method of j desiccatingj liquids, either in a-natural or condensed state, and containing either, animal or vegetable matter, and an object of the invention is ameth od whereby the constituent solids of such .matter may be rapidly and practically completely recovered in the form of a substanti powder. A further object is a method whereby a. greater desiccated than is possible with known apparatus utilizing an'equal volume. of heated air. Another object is a process in which the. moisture laden air is continuously removed from the desiccating chamber to provide space for inflowing heated dry air, and the chamber thus continuously maintained ina dry state.

These and other features of the process are hereinafter more fully described and claimed and an apparatus for the performance of the process is shown somewhat diagrammatically in the accompanying drawings in Which- Figure 1' afvertical section thereof.

Fig. 2"is a similar section taken at a rightv angle to that of- Fig. 1. J

Similar characters. refer to similar parts throughout the *drawing and specification.

The apparatus consists of a chamber 1 formed with double walls spaced apart to insulate the interior thereof from thelower temperature of the 'outside atmosphere.

. having a deflector plate 6 .thereon Air is supplied to the? conduit by means of a blower not shown, the air being heated previous to entering the chamber by means of steam pipes or-othei' convenient well known means. I

.The chamber at-the bottom below the discharge end of the air conduit is. provided on opposite sides with outlet conduits 7, 7', and each conduit is provided with a pair of united at the top by the bar 10 pivoted to each frame. The frames are covered with .cloth or other l'suitable screen material and between the sides and ends of the frames and the conduit wall is also inserted a loose' piece 11 ofsimilar material allowing the frames to be vibrated.- The frames are held iii-vertical position by means of a spring 12- '75 or a number of such springs, and across the 7 back of the outerframe is a rod 13 contacted by a cam 14. There is a cam 14 at each end of the frame secured toacam shaft 50,

and by revolution of the camshaft by any convenient method, the screens are forced .to the position shown by dotted lines in Fig.

1, by reason of the high points of the cams contactlng the rod 13 and as the igh points I position with suficient force' to jar, the powder from the screens.

lows :'-The .air ,is forced through the con.-

through'the pipes 3 and is sprayed into the interior of the chamber at the top through a fluid such as condensed milk it should'be maintained at a temperature of substantially 14:0degrees F. and as the fluid enters the chamber'in a finely divided state, the particles fall'through an ascending current of heated air. The air being warmer at the bottom of the chamber immediately after the particles are, therefore, completely dried by the-time they reachlthe floor of the compartment. Also as the air becomes moisture'laden it naturally falls to the bottom of-thechamber and passes out through 110 atmosphere of the compartment ismaintained in. a comparatively dry state. The

air entering the-chamber is dry, and as it passes upward from the mouth 5 of the conduit coming in contact with the spray it becomes cooled and moisture laden, and its natural path of travel is then downward and out through the screens where all float-- ing particles of dried fluid are separated from the air.

The dried particles fall to the floor of the compartment in the form of a powder and may be removed therefrom in any convenient way through a doorway, 60. The capacity of the apparatus is substantially double that of other types .using the same volume .oi heated air, as the spray is made to pass vertically through a continuously ascending volume of hot air which holds the particles in -suspension for a greater period thanis *usual whereas with most other apparatus be slightly above the plane of the upper side of the conduit 7, so that the air passing into the chamber first ascends before passing out of the conduits at the bottom. 1

From the foregoing description it be comes evident that the essential step or steps. of the process consist in spraying the liquid into and allowing it to fall through an ascending current of heated air in a cham her and removing the moisture ladenair from the bottom screens.

Having thus briefly described my process and apparatus by means or" which it may be performed, what T claim and desire to secure by Letters Patent of the United States is Y 1. In a method of desiccating fluids, the step consisting in spraying the fluid into and allowing it to fall through an ascending current of heated air in a chamber, and

discharging the moisture laden air through a screened aperture in the chamber wall" chamber, an lnlet'conduit for a1r near the near the bottom.

2. The herein described method of desiccating fluids consisting in spraying the fluid into the top of a chamber and allowing it to fall through an ascending current of heated air introducedcentrally of the bottom of the chamber, and discharging the moisture laden air through screened openings in the chamber wall near the bottom.

3. In a method of .desiccating'fluids, the

steps consisting in spraying the fluid into and allowing it to fallby gravity through a current of heated air' upwardly impelled centrally of the compartment, and removing the moisture laden air near the bottom- (at the compartment through screened openings in-the wall thereof.

into the chamber.

of the chamber through teasers eating fluids consisting in discharging the fluid in finely divided form into a chamber,

to fall through an ascending current of heated airand discharging the air through screens below the The herein described method of desiccating fluids containing animal or vegetable matter,*consisting in spraying fluidinto the point of its introduction top of a chamber at several. points and.

toward the center allowing it to fall through a current of heated air ascending'centrally of the chamber and discharging the moisture laden air from the chamber through screened openings in the periphery thereof.

6. The herein described method of -desic-, cating fluidsconsisting in'spraying'the fluid in finely divided form into the upper part of a'confined, moving, body of air continu ously renewed at a point below the ,intro- 1 duction of the fluid, and removing the moisture laden air at aipoint below'the pointof renewal.

7. Tn desiccating apparatus a desiccating chamber, means for introducing fluid in the form of a spray into the chamber near the top, and means for introducing heated air centrally into the chamber near the bottom, said chamber having an outlet in' the wall for the moisture laden air.

8. In desiccating apparatus, a desiccating chamber, means for spraying the fluid into the chamber near the top, means for introducing heated air centrally into the chamber near the bottom, an. outlet conduit for the air in the wall of the chamber near. the

bottom, and screens through which the air current of air near the top, outlet-conduits for air below the point of its introduction in the chamber and screens through which the air must pass to pass through the outlet.

'10. In desiccating apparatus, a desiccating bottom of the chamber arranged to discharge air in an upward direction centrally I of the chamber, means for forcing heated airthroulgh the inlet conduit, spraying de- -moisture and then spraying the fluid While heated to a-temperature of substantially 140 degrees into achamberand allowing it amount of the remaining mee ere f to all through an ascending current of air therein having a temperature of substantially 180 to 200 degrees F. for a distance sufficient to permit absorbtion of the desired moisture, and passing the air from the chamber through screens.
